G (x) = - 10x2 + 490

lesser x=

greater x =

Greater x = + 7

Lesser x = - 7

Step-by-step explanation:

G (x) = - 10x2 + 490

Let the left side = 0

So we have

0 = - 10x2 + 490

Solving the above now by allowing the variable with the coefficient of x cross the equal sign.

10x² = 490

Dividing by 10

X² = 490/10

X² = 49

Taking the root of both sides

X = √49

X = + 7or - 7

Bigger x = + 7

Smaller x = - 7
